POS Glass Tip Range of Liquid Level Switches

The POS Glass Tip range of liquid level switches are robust and rugged, ideal for operation in harsh industrial environments, aggressive chemicals and extreme temperatures up to 140°C.

The POS Glass Tip sensor is solid state, combining an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type, oil or water based.

Options of N and P type outputs can sink or source up to 200mA at a supply voltage range from 12 to 28Vdc and can be configured to be a high or low signal in either a wet or dry state. The sensor is available with a M12 connector or 3 core cable and also has LED output indication.

The stainless steel body combined with a crystal glass sensing tip allows the POS Glass Tip range of liquid level switches to operate under high pressure conditions up to 80 bar and across two temperature ranges; Standard (-40 to 100°C) or Extended (-40 to 140ºC).
